“VEK” LLC actively works in the market of polymers of Uzbekistan. Our company specializes in and around of production of aqueous polymeric dispersions for use in the building, paint and varnish, textile, furniture, printing industry. On basis of polyvinyl acetate dispersion, producible by “VEK” LLC produced varieties of the glue compositions which are replacing import substitution products. At present “VEK” LLC has a considerable segment of stable delivery of varied and required marketable products on all across the Republic.

Uzacryl M20 – is a plasticizer-free aqueous and an average viscous dispersion of a copolymer of acrylic ester and styrene. It became a universal basis for reception of fine coverings under operational characteristics on a wood, concrete, brick and metal.

PVA VP

GLUE VP (PVAD)

Polyvinyl acetate dispersions (PVAD) - are products with extensive ranges of application in the most various spheres. It represents a viscous white single liquid with a relative density of 1.1 g/sm3, being a product of polymerization of vinyl acetate in an aqueous medium in the presence of emulsifying agent and initiator of a polymerization, admixed with plasticizer or without it.

Plasticized dispersion is ready for application, possesses practically infinite life, is nontoxic, and differs with elasticity and stability of a glue line, light and fungus resistance. Due to universal adhesive and bonding properties, firmness to ageing, a high gluing ability and ecological compatibility polyvinyl acetate dispersions are widely applied in industry, building and in a life. Not without reason this unique product is said the material of «thousand possibilities».

Ranges of application

PVAD VP – is general-purpose binder, mainly used for the following applications.

― As a glue at manufacturing various leather accessories (handbags, purses, etc.)

― As an adhesive for a paper, cardboard, wood, plywood and cotton, at production of tare and packing from a paper and cardboard, a corrugated cardboard and wood, and also for gluing labels (except the food-processing industry)

― As a binder in water emulsion paints

― As a glue at production of binding-stitching works

― As a glue for tare from a paper, cardboard and tree, intended for packaging of foodstuff provided that they not contact with a glue, and also tare for clothes, footwear and etc.

― As a glue for facing ceramic floor and front tiles, as a finishing agent for fabric finishing; in production of fibre glasses and canvas glasses

― As a polymeric coating in materials for inner details of footwear

― As a sizing agent by production of a shoe board

― As a binder at manufacturing glue for furniture industry

― As a glue in production of tobacco goods

Processing

Before using the PVAD VP it is necessary to blend or shake. Bonding surfaces pretreat from dust, resin, fat stain and other contaminants. It should be thin on one of the gluing surface, thereafter connect with other and slightly press. At increased requirements to bond strength, the PVAD VP should coat on both bonded surfaces. As far as possible put them under press. Glue consumption makes 50-300 gr. on 1m² depending on the structure of bonded bases. Recommended temperature must not be below +10 °C, relative humidity above 80%. In stated conditions dispersion dries up in a day after coating.

Safety

General

In process of recycling should be provided effective ventilation and personal skin protection equipments and safety glasses. In case of eye/skin contact with a product rinse your eyes/skin in plenty of water. PVAD VP is nonhazardous. On toxic properties labels to 3 class - product is moderate dangerous.

Storage

PVAD VP should be stored in a tightly closed container in a dry place at temperature not below +5 °C. It should not be exposed to powerful heating and freezing. PVAD VP at temperature below 0 °C freezes and irreversibly loses quality and properties. It has a shelf life of 12 months from the manufacturing date.

Packaging

All dispersions produced by the company are packaged in modern plastic containers in weight on 800 gr. and in industrial containers: plastic barrels with capacity from 40 to 60 kg. or steel barrels with capacity 200 kg., as well as in any other form of packaging under the agreement with consumer
